White Tea Standards: What the Two Documents Cover

Two documents govern white tea. GB/T 22291-2017 sets the product standard: terminology, classification, grades, moisture and ash limits, test methods and inspection rules. GB/T 22109-2008 is the geographical indication standard that protects the Fuding name. They answer different questions, and neither controls price or the marketing use of a grade word.

The 2017 revision of the product standard is the one that matters most to buyers, because it redefined Gongmei. Before it, Gongmei and Shoumei were distinguished by grade; after it, Gongmei is defined by bush, as the tender shoots of the population variety known as Cai Cha.

That single change is the most consequential thing in white tea regulation in decades, and it is still not universally observed on retail labels.

What each document governs

The product standard divides white tea into four grades: Silver Needle, White Peony, Gongmei and Shoumei, plus new craft white tea as a separate product within the category. Each grade has a sensory description and a set of physical requirements.

The requirements that can be measured are the enforceable core. Moisture must be below a stated percentage, total ash below another, and the tea must be free of foreign matter. These are the clauses a laboratory can test and a dispute can turn on.

The sensory descriptions are qualitative and describe the dry leaf, the liquor, the aroma and the infused leaf. They are the part a drinker cares about and the part that is hardest to enforce.

The geographical indication is a different instrument. It defines the Fuding boundary, lists the permitted bushes and sets requirements for production within it, and it gives registered producers the right to use a mark.

The Gongmei redefinition

Before 2017, Gongmei and Shoumei were separated by quality and leaf size, and the terms were used loosely and interchangeably across the trade. The 2017 standard ended that by tying Gongmei to a bush.

Under the current definition, Gongmei is made from the tender shoots of the Cai Cha population variety. Shoumei is made from the older leaf of the improved cultivars, Fuding Da Bai and Zhenghe Da Bai. The two are now different products rather than different grades of one.

The practical effect is that a tea sold as Gongmei should come from Cai Cha, and a tea from Fuding Da Bai leaf cannot claim the name regardless of its grade. Many sellers have not adjusted, and a great deal of what is called Gongmei is Shoumei by the current definition.

The redefinition also gave the old population bush a protected status of its own, which matters because Cai Cha was being replaced by higher-yielding cultivars. A name that had been fading acquired a legal reason to exist.

• GB/T 22291-2017 is the product standard, not 2018.
• Gongmei is now defined by bush, as Cai Cha tender shoots.
• Shoumei is older leaf of the improved cultivars.
• GB/T 22109-2008 protects the Fuding name and boundary.
• Neither standard sets price or controls marketing language.

How grading is carried out

Grading happens against the sensory descriptions in the standard, using a fixed procedure. A weighed sample is brewed in a standard vessel, the liquor is poured off, and the leaf, the liquor and the aroma are each assessed against the written description for that grade.

The assessment covers the dry leaf, the liquor, the aroma and the infused leaf. Each is scored, and the total places the batch in a grade. Two graders work independently where the stakes justify it.

The procedure is designed to be repeatable across factories and counties, which is what lets a wholesaler in one province order by grade from a factory in another. It is not designed to find the best tea, only to place a batch in the right box.

A consequence is that an unusual tea scores poorly. A Silver Needle with an unexpected floral note and a light body may fail the description of Silver Needle and be graded down, even though a drinker might prefer it. Grading rewards conformity.

The other consequence is that grade and price diverge. Nothing in the procedure considers scarcity, origin or fashion, and the market prices all three. A grade one tea from a famous county costs many times a grade one tea from an obscure one, and both are correctly graded.

What the standards do not cover

They do not set prices. A grade one Silver Needle from Fuding and one from a lesser county are both grade one and can differ in price by a factor of five, and no document addresses the gap.

They do not regulate the word premium, reserve, or any of the other adjectives on a tin. Those are marketing terms with no legal meaning, and a buyer who reads them as grades is reading them wrongly.

They do not verify age. A vintage claim is outside both documents, and the ageing market operates entirely on seller reputation and on the buyer’s ability to judge a cup.

They do not guarantee that the tea in the tin matches the batch that was tested. Inspection is sporadic at the retail level, and a standard number is a claim rather than a certificate.

What they do provide is a shared vocabulary. A producer, a wholesaler and a buyer can all refer to Gongmei or Silver Needle and mean roughly the same thing, which is a modest achievement and the foundation of trade at a distance.

The other rules that sit alongside

Each layer is verified by a different mechanism and each is worth a different amount. A buyer who can tell them apart reads a label far better than one who treats every mark as equivalent.

The geographical indication is the strongest of the four for origin, because the boundary is defined and the registry is public. It is also the smallest, since it covers only Fuding among the producing counties, and a Zhenghe tea cannot carry it however good it is.

Organic certification is the weakest for quality and the strongest for growing method. A certified white tea is not thereby a better tea, and an uncertified one may be excellent.

Why the 2017 revision happened

The revision followed two decades of confusion. Gongmei and Shoumei had drifted until the words meant whatever a seller wanted, and the market had no way to settle a dispute about which one a batch was.

The Cai Cha population bush was also under pressure. It yields less than the improved cultivars and was being replaced in many gardens, and a name tied to it gave growers a reason to keep it. The redefinition was as much a conservation measure as a commercial one.

A third pressure was export. A standard that could not distinguish its own grades was hard to defend in a shipment dispute, and the revision gave exporters a document to point at.

The result is a clearer standard and a market that has not caught up. A buyer today will meet sellers using the old definitions, and the standard is the only way to know which one a label is using.

The practical advice is to read a white tea label for three things: the grade word, the county and the year. The grade word is regulated, the county is partly regulated, and the year is not regulated at all, and knowing which is which tells you how much of the label to trust.

That is a small habit and it is the most useful thing the standards offer a retail buyer, because it turns a page of print into three claims of unequal weight.

One further point about the geographical indication deserves a line. Because only Fuding holds one among the white tea counties, a buyer who sees a mark is looking at a Fuding tea, and a buyer who sees none may be looking at a Zhenghe or Jianyang tea that is equally good and has no protection to cite.

The standards, in the end, regulate the vocabulary of white tea rather than its quality, and that is what a standard can do. The cup remains outside every document.
